DOUGH-RAlSER.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed December 28, 1904. Serial No. 238,570.

To (r25 whom, it may concern.-

Be it known that I, WILLIAM H. H01.-

LANDER, a citizen of the United States, re-- siding at Evansville, county of Vanderburg, and State of Indiana, have invented. certain new and useful Improvements in Dough- Raisers, of which the following is a specification.

My invention relates to dough-raisers and the object of the invention is to provide a device of this character which wiil be compact and handy and which will perform the essential functions of such device in a capable and efiicient manner.

A further object of the device is the provision of means whereby two compartments may be heated independently or separately at the same time or at difi erent times.

The invention consists in a rectangular casing in which there are two compartments and a eombustion-cornpartment and means for dividing the two com artments, so one can be heated while the otl icr remains idle.

In the drawings which form a part of this a lication Fi ure 1 re resents a 'ers ecti ir ii view df th e device iivith the lid of the dough-trough raised and the door of the com bustion-chamber 0 )en. Fig. 2 represents a vertical section of t e device; Fig. 3, a transverse section on lines w :c of Fig. 1 3 and Fig. 4 a transverse section on lines 3 y, Fig. 1.

Referring more particularly to the drawings, 1 represents a casing of suitable length, breadth, and depth, which is provided at with a door leading into the combustionchamber 3. This combustion -chamher 3 communicates with a tubular member 4, having apertures 5 adapted to allow the heat from the lamp 6 to penetrate the compartments 7. These compartments 7 are provided with shelves 8 and a top 9, which separates them from the rest of the structure. The tubular member 4 is slanted inwardly from a point 10 to the top 9 and forms a conical flue 11, which is provided at its upper portion with shields 12, ada ted to prevent excessive heat at the point 0' intersection of the top 9 and the partitions 4.

Spaced from the sides, front, and back of the casin 1 above the top 9 is a dough trough or ox 13, which is held from engagement with the sideshy strips 14 and raised above the up er edge of the outside casing and connectecItherewith at the top by means of strips 15, having heat-outlet apertures 16. Secured to these strips and to the outside of lap the outside casing.

the casing by strap-hinges is the lid 17, which covers the dough-trough, but does not over- This is done so as to prevent return of the escaping heat through the apertures 16, and the dough-trough is raised above the outside casing, so that should the lid lap over the heat will not be prevented from escaping. In the conical heat-flue there isplaced a damper 18, which is adapted to close the flue 11 to prevent the heat from comin in contact with the doughtrough i3 and which forces the heat through the apertures 5 into the compartment 7. When the damper is turned so as to allow the heat to pass up around the compartment 11, it strikes with great force against the under side of the dough-box 13, and I therefore provide a shield 19 of any suitable substance. This is secured to the under side of the doughboX and prevents burning of the wood from excessive heat thereon. 20 represents a door which gives access to the compartment 7. In the iid 17 I have shown several apertures 21, which are adapted to give vent to the vapor or air which ini ht arise from the dough or yeast in the dong i-hox.

Itwiil he clearly understood that I need not use a lamp, but may use any suitable means for heating purposes, such as a gas-jet or charcoai the or such other means as I might deem best to use.

The operation is as follows: The dough or yeast is placed within the dough box or compartment 13 and the lamp ii hted and the damper opened, so as to direct the heat against the bottom of the box. As it strikes against the shield 19 it is deflected and passes up around the sides of the dough-box 13 and out the apertures 16 in the strips 15. At night flour and yeast may he placed in the dough-box 13 in separate compartments or rece tacles and the yeast allowed to rise over nig t. In the morning the flour and yeast are mixed in the same chamber and aliowed to sit therein until the dough rises. It is then made into leaves and placed in pans and put into com partnients 7 on shelves 8 to rise again, the damper being closed to drive the heat through the apertures 5 into these compartments.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a device of the class described, the combination with a casing and means for heating the interior of said casing, of a dough-box within said casing and separated therefrom, said dough-box being raised above the casin means connecting the easing to said doug -box at the top, said means provided with outlet-apertures for the heat, and a lid for said dough-box.

2. In a device of the class described, the combination with a casing and means for heating the interior of said casing, of a dough-box Within said casing and separated therefrom, said doughbox being raised above the casin beveled strips separating the casing and t e dough-box and connecting them together at the to of said casin and dough-box, said bevele strips provide with heat-outlet apertures, and a top adapted to close the dough-box.

3. In a device of the class described, the combination with a casing, of a combustionchamber therein, a plurality of compartments therein, one of said compartments be- 20 ing separated from the casing, the other of sald compartments being provided with shelves, a flue running through one of said compartments provided with apertures adapted to direct air into the compartment flue runs, and a shield protecting the bottom 0 of the separated compartment.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

WILLIAM H. HOLLANDER.
